Unwanted muscle weaknesses are uncommon. If any should occur that lead to eyebrow droop, mouth droop, double vision, asymmetric facial expression, or others, do not be alarmed. Most problems can be handled easily. Call the office at once and come in to be seen. If there is any bruising, you may apply ice as instructed above. The bruising will resolve in a few days. Makeup can be applied over this as well.
